Deciduous refers to trees and plants that shed their leaves annually, typically in the fall. This process helps them conserve water and energy during the colder months when sunlight is limited. Common examples of deciduous trees include oak, maple, and birch, which display vibrant colors before their leaves drop. In contrast to evergreen trees, which retain their foliage year-round, deciduous plants go through a cycle of growth and dormancy. During spring and summer, they flourish with lush green leaves, providing shade and habitat for various wildlife. This seasonal change is a vital part of many ecosystems, contributing to biodiversity.
